QUESTION 42A customer has deployed an N+N redundant wireless infrastructure. In this deployment, the access points have been salt and peppered between controllers. What configuration would be necessary to cut down on the use of mobility tunnels for voice clients?

QUESTION 45The AP has been configured property for a VoWLAN survey.The RF environment contains a noise of -87 to -90 dBm. What is the target value for the cell edge reading?

A. -62 dBmB. -67 dBmC. -60 dBmD. -70 dBm

Answer: B

QUESTION 46An 802.11n implementation is being discussed. Users are satisfied with the potential 300- 450 Mbps throughput of new 802.11n APs. Which three bandwidth requirements are used to calculate per client bandwidth through an 802.11n AP network? (Choose three.)

A. 450 Mbps throughput is the client max for 5-GHz radio.B. Channel bonding on 5 GHz is required for a client to have a 300 Mbps WiFi link.C. 300 Mbps throughput is the client max for 2.4-GHz radio.D. The remaining bandwidth is divided per device when more clients are connected to one AP.E. 100 Mbps Ethernet switch port is a potential bottleneck.F. CleanAir helps clear noise for 802.11n channel bonding to work.

Answer: ACD

QUESTION 47An engineer is performing a predictive wireless design for a carpeted office space, which requires voice capability and location services. Which two requirements are inputs to the design? (Choose two.)

QUESTION 48You have a customer that is building a new campus of four 3-story buildings that you have just completed the site survey for. The customer is interested in the mount of rack space they will need to allocate in either the building MDF or in the data center for controllers. Each building is going to require 75 APs to support voice and data. How should the controllers be deployed to provide the least number of controllers, the highest redundancy, and the easiest management?

A. Use the centralized deployment method in the data center with the N + N redundancy method.B. Use the centralized deployment method in the data center with the N + 1 redundancy methodC. Use the centralized deployment method in the data center with the 1 + 1 redundancy method and clientSSO.D. Use the distributed deployment method in each building MDF with the N + 1 redundancy method.E. Use the distributed deployment method in each building MDF with the N + N + 1 redundancy method.F. Use the distributed deployment method in each building MDF with the N + N redundancy method.

Answer: C

QUESTION 49What are two advantages of conducting an active survey versus a passive survey when verifying RF coverage? (Choose two.)
